stack-protector: Fix test with 32-bit userland and CONFIG_64BIT=y
When building a 64-bit 4.18-rc1 kernel with a 32-bit userland, I noticed that stack protection was silently disabled. Adding -m64 in gcc-x86_64-has-stack-protector.sh fixed that, similar to what has been noticed in commit 2a61f4747eea ("stack-protector: test compiler capability in Kconfig and drop AUTO mode") for gcc-x86_32-has-stack-protector.sh.
